Benchmarks Compared For Kernels 2.4.25 and 2.6.4

Posted by timothy on from the cheaper-than-a-chip-upgrade dept.

Josh MacLean writes "I noticed a link to an interesting article over at OSNews comparing performance of Linux kernels 2.4.25 and 2.6.4. While the workstation benchmarks are rather mundane, the server benchmarks (including Apache and MySQL) proved to be quite interesting. The rest of the Linux geeks might appreciate this. The comment thread that's linked on the last page is turning out to be relatively amusing as well."

    Interesting that they turned off the preemptible kernel, in light of what's being said on the kernel lists. I'd like to see this same suite of benchmarks with that feature turned on...

      IIRC, it was about 10% faster. Not all that much.

      Ah but what was being discussed on the list was that kernel preempt makes the kernel SLOWER. I believe it was Andrea Arcangeli that was saying it was slow.

      Lessee.... link, link... ah, there: link

    I have wondered for some time how much of an advantage the 2.6 kernel would be. This clearly shows--at least for dual Xeon systems--that the 2.6 kernel does some excelent stuff for Samba, and seems great for MySQL, while only marginally better for the other tests (and sometimes worse). Someone should do similar testing with various processors. I would be interested in seeing how different it is for the Pentium 4 (with hyperthreading) and Athlon XP, especially.
